Fuel cell stacks are made of NINE membrane electrode assemblies (MEAs) interleaved between TEN bipolar plates (BPs) as illustrated below. The width of a membrane electrode assembly and a bipolar plate are normally distributed with μMEA=0.15 σMEA=0.01 and μBP=5 σBP=0.1 respectively. The widths of the different layers are independent of each other.
Which ONE of the following represents the CORRECT values of (μstack,σstack) for the overall fuel cell stack width?
Correct : a
